' lhis invention relates to transportation f of two of the bodiesefe carunit..

Another object of the linvention is to prole n side hearing for nnarticulated eur comprising u resilient member mounted on n truck undloosely engaging the adjacent ends of two of the bodies: of the cur.

A further object of theim'ention-is to lprovide a side bearing for nn'irtienlnted enr which comprises :i member extending between und :it itsends engaging the. ndjzb cent ends of two bodies of lthe car and between its ends engaging en adjacent cur truck. v f

A further object of the invention is to provide :1 side bearingi for the.nljilmeni. ends of two bodies of an nrtienlntwl cnr having a resilientportion adapted to he enf-'Jlged by Said ends under lnornnil serviceconditions, and having` n' rigid' portion adapted to be engaged by saidendsA in the event of. the breakage or failure nl' Isnid resilientportion. y

accident with the consequent -injuryk'or--loss' or broken the body orbodies will 'move i L'90.

Each ot these members gis hollow f a bottom 10, spziced sides l1 endend'walls 12, all of which are preferably integral.. The z..

side walls 11 extend vertically. somedist'nc'c above the bolsterfa'ndlongitudinally they preferably extend on each side of thefbol ter zrsufficient di'stnnce that their end portionsv 13 are under the adjacentends of the bodies but are of such a. height that they are net inengagement therewith under normal service conditions.

The side bearing members Y8 extend between the adjacent ends of adjacentbodies and each preferably comprises a spring; made up of a plurality ofspring plates '1440i vatying lengths which are securely held together,one on top of the other, through the medium of a spring band l5. Thelower portion of thisl spring band extends between spaced upwardlyextending lugs 16 formed on lthe bot-tom 10 of the member 9, and belowthe upper edges of such -lugs,vthis band rests on shims 17 arrangedbetween the lugs,

which ehims may be removed or replaced through an opening 18 formed inone of the sides 11. ltwill be understood that in some rases these shimsmaybe omitted and the lower portion of the spring band may rest direct-.y upon the bottom 10 between the lugs 16. The inner surfaces of thesides 11 on both sides of the center of their length are offset to formchannels 18 which channels vary in width from their narrowest portionsadjacent the bottom l() to their widest portions above the bottom l0.These channels 18 are for the reception of the sides of the spring bands15 and w ien the side bearing member 8 is mounted in the base member 9,it will be permitted to cant or rock slightly in the direction of itslength and yet will not become a.,eidentally .separated from the base 9.f

The end portions of each-o the side bearing members 8 extend above theupper edges of the sides l1 of the base member 9 and have mounted onsuoli portions, shoe members 19, the upper surfaces of which are adaptedto be engaged by the ends of the adjacent car bodies. These shoe membersrest on the member 8 and arepermitted to4 rock relative thereto'in thedirection-oi the length of the member. Each of the shoe members isprovided with sides Q0 which extend downwardly between the' sides 1l ofthe base 9 and are adapted to cooperate with .oi the shoe relative tothe member 8.

prevent the shoes from moving in directions away fromeach other;

It will be noted that as the side bearino members 8 are resilient,and'looselymounted on the truck, and that the shoe members 19 are pivotaly mounted on the members 8, and are held against excessive longitudinalmovement, a proper bearing between the adjacent lfailure of the ,firstmentioned side bearing menten car bodies and the truck is insured at alltimes and under all service conditions.

1n Figs. and 9 a modification ot the invention illustrated in-which eachof the shoe members I9, in the event of the failure. of the side bearingmember, will rest upon and be supported. y the members 9'in such amanner that the bearing' surfaces of the shoe members will be slightlyhigher than the upper surfaces of vthe member 9, so that these bearingsurfaces are adapted to be engaged by the bearing surfaces on thebodies, and thus support the ends of the bodies.'

It will also be noted by those skilled in the art to which thisinvention appertains that changes may be made in the details of theseveral parts forming the invention without departing from the spiritand scope of the appended claims.
